示例1: testIt
# 需要导入模块: from PySide2.QtCore import QObject [as 别名]
# 或者: from PySide2.QtCore.QObject import emit [as 别名]
def testIt(self):
global called
called = False
o = QObject()
o.connect(o, SIGNAL("ASignal"), functools.partial(someSlot, "partial .."))
o.emit(SIGNAL("ASignal"))
self.assertTrue(called)示例2: testSharedSignalEmission
# 需要导入模块: from PySide2.QtCore import QObject [as 别名]
# 或者: from PySide2.QtCore.QObject import emit [as 别名]
def testSharedSignalEmission(self):
o = QObject()
m = MyObject()
o.connect(SIGNAL("foo2()"), m.mySlot)
m.connect(SIGNAL("foo2()"), m.mySlot)
o.emit(SIGNAL("foo2()"))
self.assertEqual(m._slotCalledCount, 1)
del o
m.emit(SIGNAL("foo2()"))
self.assertEqual(m._slotCalledCount, 2)示例3: testDisconnectCleanup
# 需要导入模块: from PySide2.QtCore import QObject [as 别名]
# 或者: from PySide2.QtCore.QObject import emit [as 别名]
def testDisconnectCleanup(self):
for c in range(MAX_LOOPS):
self._count = 0
self._senders = []
for i in range(MAX_OBJECTS):
o = QObject()
QObject.connect(o, SIGNAL("fire()"), lambda: self.myCB())
self._senders.append(o)
o.emit(SIGNAL("fire()"))
self.assertEqual(self._count, MAX_OBJECTS)
#delete all senders will disconnect the signals
self._senders = []示例4: TestSignalsBlocked
# 需要导入模块: from PySide2.QtCore import QObject [as 别名]
# 或者: from PySide2.QtCore.QObject import emit [as 别名]
